# The +UnitMeasurements::Rails::ActiveRecord::Volume+ module provides a convenient
# way to define volume-measured attributes in +ActiveRecord+ models.
#
# It acts as a wrapper for the +measured+ method, simplifying the definition of
# volume-measured attributes without directly invoking the +measured+ method.

module UnitMeasurements::Rails::ActiveRecord::Volume
# @!scope class
# Defines _volume-measured_ attributes in the +ActiveRecord+ model.
#
# This method serves as a wrapper around the +measured+ method and allows easy
# definition of volume-measured attributes by accepting an array of attribute
# names along with their options.
#
# @param [Array<String|Symbol>] measured_attrs
# An array of the names of volume-measured attributes.
# @param [Hash] options A customizable set of options
# @option options [String|Symbol] :quantity_attribute_name The name of the quantity attribute.
# @option options [String|Symbol] :unit_attribute_name The name of the unit attribute.
#
# @example Define single volume-measured attribute:
# class Container < ActiveRecord::Base
# measured_volume :total_volume
# end
#
# @example Define multiple volume-measured attributes:
# class Container < ActiveRecord::Base
# measured_volume :internal_volume, :external_volume
# end
#
# @return [void]
